Travel eSIM, paid in USDC

Get Connected

Browse, pay, and connect in under two minutes.

blocfone® is a data eSIM you buy and activate with USDC — it eliminates roaming charges, with no contracts and no account needed.

Find a plan, pay with stablecoin, and get your eSIM activation code in the web agent or in Telegram — all you need is your phone and a Solana-enabled wallet, or we’ll create one for you by connecting with Google or Apple in the web agent. If delivery ever fails, you get an automatic refund.

How it works

The Essentials

Everything happens in the web agent or in Telegram.

1 — Open
Open the web agent or Telegram bot and browse the available data plans.
2 — Pay
Checkout and deposit USDC into the smart-contract until your eSIM is successfully delivered.
3 — Connect
Receive your eSIM activation code — QR code, server address, and token — without leaving the web agent or Telegram.
4 — Manage
Check your remaining data anytime under My Orders in the web agent or in the Telegram bot, and top up with USDC in a tap when you’re running low — no new eSIM, no reinstall.
5 — Eliminates roaming charges
Without opening a new account or providing identity paperwork.
6 — 8 languages
The web agent and Telegram bot are available in eight languages.

Stay topped up

Stay topped up

Your data, always in view.

Open the web agent or Telegram bot to see exactly how much data you’ve used and how much is left. When you’re close to empty, top up in USDC and keep browsing.

The data is added to the eSIM you already have, so there’s nothing to reinstall and no new activation code.

Private by design

Your Data

No personal information required.

blocfone® has no advertising, no subscription, and no requirement to collect personal information.

You buy connectivity directly from your Solana wallet to get online, or we’ll create one for you by connecting with Google or Apple in the web agent.
